I did pull the two geared shafts out of the cover one of which looks as if it has the clutch on it but I didn't separate/open the assembly and am reluctant to pull it apart to look. Should have looked for "How to" videos before I started, the Paul Compton videos are very good and would hav...

Found the dowels and it's not one them, they are about O.D. 12mm I.D. 8mm.

Thank you Steve for saying that, it's what I have been thinking but I did look at the case and didn't see anywhere it would fit I could have missed it of course. I also checked the parts list and it didn't list any dowels/bushes for left hand cover or the crank case but did list 2 for the for the ri...

I'm changing the clutch seals on a 501 Excalibur due to finding the clutch bathing in i/2 a pint of oil. When checking and cleaning parts prior to refitting I found a bright steel bush O.D. 9mm, I.D 7mm, L 7mm; it was in the tray where I had put the clutch hub, push rod, seal, etc but I don't think ...

I have not had time to do any work on the 501 this work but it I have been wondering why they needed to develop this air box, which obviously took time and expense, at a time when it seems development in other areas had largely come to a halt. That the air box/silencer combination works well is not ...

I'll have to give this some thought, the air box is heavy, complex and appears to be designed to stop air reaching the carbs in sufficient quantities. If the 501 engine really needs this air-box to make it work in an acceptable way, then what is so different about this particular engine; other versi...

Thanks for the replies, both the air filter and exhaust are stock at the moment but I don't think they will stay that way for long.

As part of giving the the 501 a check over I stripped the carbs and was happy to find everything clean and almost no wear on slides etc, only one thing seemed out of place, the main jets are 76. I checked the specs with the archived Netherlands Club site and 76 appears to the stock size. This seems ...

Thanks for the reply John. Thanks for the info, the starter tip is on my to do list. Still not sure which rear sprocket to use, 42 teeth looks reasonable, I'll probably try that.

Thanks for replies. Is it a series 1 or 2 ? I don't know how to tell the difference, I can say date of manufacture on V5 is 1990, it has a kokusan bottom end, Galardoni barrels and 28 phbh carbs and the engine breather pipes all go to a box under the seat with a single outlet if that helps to tell t...

Italian V twins that is. I enjoyed the 350 over the summer but having just sold my Moto Guzzi S3 after 42 years ownership I was able to fill the hole left in the garage with an Excalibur 501. It needs a little work but nothing major I think. When I was making up my list of jobs to do over the winter...

Update. I gave up on the PHBL carbs it was costing me a fortune in jets, in the end I fitted a pair of VHB carbs from a Ducati and they worked well with sport jetting and the bike ran well over the summer.

Thanks for the replies. The problem I had was that the set up shown on the Dutch website and other places were either for VHB carbs or PHBL carbs fitted to 500's; that's good for idle & main jets but no help for needle or emulsion tube sizes. I have now found a chart on the forum that suggest th...

I need a bit of advice about 350 Excalibur carburation. How and why I have an Excalibur when I had no intention of buying one still puzzles me but these things do happen from time to time. The previous owner told me he thought the carbs needed balancing, after riding a 100 miles or so home I was in ...
